본 연구는 방풍나물의 인공광 식물공장에서 재배시스템에 따른 생육, 비타민 C, 아미노산함량, 수량에 미치는 영향을 구명코자 실시하였다. 박막수경(NFT), 배지경 (Perlite), 분무경(Aeroponics) 등 3처리를 하였다. 초장은 NFT 처리에서 10.2cm 가장 길었으며, Perlite 처리에서 8.9cm로 가장 짧았다. 주당 엽 생체중은 Perlite, NFT, Aeroponics순으로 무거웠다. 총 페놀 함량은 Aeroponics가 117.84mg·100g-1 GE로 가장 높았고, NFT 98.57mg·100g-1 GE, Perlite 74.62mg·100g-1 GE 순으로 재배 방법에 따라 차이를 나타냈다. 총 플라보노이드는 Aeroponics에서만 0.12mg·100g-1가 검출되었으나, NFT와 Perlite 처리구에서는 검출되지 않았다. 비타민 C 함량은 Aeroponics가 108.23mg ·100g-1으로 가장 높았으며, Perlite가 88.05mg·100g-1, NFT가 80.83mg·100g-1으로 처리에 따라 통계적인 유의성을 나타냈다. 총 식이섬유소 함량은 Aeroponics가 Perlite와 NFT보다 높았다. Cystein 함량은 Aeroponics에서 46.76mg ·100g-1로 가장 높았으며, methionine 함량은 Perlite가 75.64mg·100g-1 로 가장 낮았다. 무기질 함량은 모든 처리에서 K, Ca, P, Mg 순으로 높았다.

시로미 열매 추출물의 라디칼 소거 활성과 간 손상 동물모델에서의 항산화 효소 활성 측정을 통해 추출물의 항산화 효과를 평가하였다. In vitro 실험에서, 시로미 열매 추출물은 12.0 ug/ml의 농도에서 DPPH 라디칼을 50% 소거하는 활성을 보였고, 1 mg/ml의 농도에서 56.1%의 지질과산화 억제 활성을 나타내었다. 그리고 CCl4로 유도한 간 손상 동물모델에서 serum ALT 및 AST의 수치를 감소시켜 간보호 효능을 나타내었고, 간 조직의 지질 과산화를 최대 73% 억제하였으며, 항산화 효소인 SOD 및 catalase의 활성을 유의적으로 증가시켰다.

The volatile aromatic substances from Cinnamomum camphora and C. japonicum among warm-temperate tree species were examined for the physiological and psychological effects on the human body. Each scent of the trees was provided to the test materials. And then their brain wave, pulse rate, aroma sensibility evaluation and POMS were measured as follows. To examine psychological effect of aroma of each tree species on human bodies, aroma sensibility evaluation and POMS were conducted. The result reveals that the aroma of the two tree species were interpreted in terms of comfort, naturalness and stimuli, and that C. camphora shows low level of satisfaction due to strong aroma while C. japonicum is more preferred due to its soft and fragrant aroma. As well, POMS was given to identify subjects' temporary emotional state. The result indicates that C. camphora has higher values in every item than C. japonicum, and that both tree species repress anxiety and depression and create vivacious feelings with higher values in [vivacity] and [anger-hostility] items than [tense-anxiety] and [distress-depression]. To examine the physiological effect of aroma of each tree species, aroma extracted from the two tree species were distributed, and the subjects' brain wave and impulse were measured. The result demonstrates that C. camphor has relaxing effect of increasing α-wave and reducing pulse, and that C. japonicum also has relaxing effect, but the effect is less than that of C. camphora as it reduces pulse though it slightly reduces α-wave. In addition, individual preferences for C. camphora vary as it has big individual deviations vary, but C. japonicum has similar level of preference as its variances are small. The natural and pleasant aroma of these two tree species seem to have tranquilizing effect in both the physiological and psychological aspects and are found to have positive effects of feeling refreshed, feeling enhanced, and so on. In conclusion, there is a sufficient possibility of developing these two aromatic warm-temperate tree species. Also, the importance of such difference between these two tree species lies in the fact that they can set standards for the utilization of warm-temperate forest in the future.
